Description

Technical Field

[0001] This application relates to the field of glass container technology, and in particular to a glass container. Background Technology

[0002] Glass containers are widely used for packaging wines, beverages, perfumes, and other products due to their high transparency, chemical stability, and elegant appearance. For some high-end products packaged in glass containers, to meet the higher requirements for aesthetics, sophistication, and lightweight design, the glass containers are typically designed with extremely thin walls.

[0003] The glass containers widely used in daily life have relatively thick walls and are mostly made by blow molding. However, due to the limitations of the blow molding process, these thin-walled glass containers cannot be made by blow molding. The common method is to make the individual walls of the thin-walled glass container in pieces and then connect the individual walls by a welding process.

[0004] When a product is packaged in a thin-walled glass container, the container is sealed. However, due to factors such as the evaporation of product components or fermentation, the internal pressure of the thin-walled glass container can change. Because of its thin walls, the thin-walled glass container has lower mechanical strength. When external air pressure fluctuates or the internal pressure changes, the thin-walled glass container is prone to rupture under pressure, resulting in compromised product safety. Summary of the Invention

[0005] Therefore, it is necessary to provide a glass container and its processing method to address the problem that thin-walled glass containers are prone to breakage under pressure when there are fluctuations in external air pressure or changes in internal air pressure, which leads to poor product safety.

[0006] One embodiment of this application provides a glass container, the glass container including: a top wall, a bottom wall and a plurality of side walls connected end to end in sequence, the bottom ends of the plurality of side walls are all connected to the bottom wall, and the top ends of the plurality of side walls are all connected to the top wall, so as to define the receiving cavity of the glass container;

[0007] At least one of the sidewalls has a wall material morphology that has at least one convex portion and at least one concave portion, the convex portion having a first outer surface facing outward of the receiving cavity and a first inner surface facing inward of the receiving cavity, the first outer surface protruding outward of the receiving cavity and the first inner surface concave outward of the receiving cavity;

[0008] The concave portion has a second outer surface facing the outside of the receiving cavity and a second inner surface facing the inside of the receiving cavity. The second outer surface is recessed towards the inside of the receiving cavity, and the second inner surface protrudes towards the inside of the receiving cavity.

[0009] In one embodiment, the sidewall includes a flat plate portion; the flat plate portion, the convex portion, and the concave portion are integrally formed.

[0010] In one embodiment, the convex portion and / or the concave portion defines an internal region;

[0011] The plate portion includes a first portion located in the inner region and a second portion located outside the inner region.

[0012] In one embodiment, along the direction of enclosure of the inner region, the convex portion extends to form a circumferential closed structure, the concave portion extends to form a closed structure, and the convex portion and the concave portion are adjacent to each other.

[0013] In one embodiment, the sidewall having the convex portion and the concave portion has a plate portion whose thickness H satisfies the condition: 1.5mm ≥ H ≥ 0.05mm.

[0014] In one embodiment, the vertical distance B between the highest point of the first outer surface and the lowest point of the second outer surface satisfies the condition: B > 1.5H, where H is the thickness of the plate portion, and the vertical distance B refers to the distance between the highest point and the lowest point along the thickness direction of the plate portion.

[0015] In one embodiment, there are multiple convex portions and multiple concave portions, and the convex portions and concave portions are arranged alternately in sequence; the convex portions and the concave portions are adjacent to each other.

[0016] In one embodiment, the distance D between the highest points of two adjacent convex portions satisfies the condition: 8B > D > 2B, where B refers to the vertical distance between the highest point of the first outer surface and the lowest point of the second outer surface.

[0017] In one embodiment, the plurality of sidewalls includes two first sidewalls facing each other along a first direction and two second sidewalls facing each other along a second direction, the first direction intersecting the second direction; the width of the first sidewall is greater than the width of the second sidewall, and the thickness of the first sidewall is less than the thickness of the second sidewall;

[0018] Both first sidewalls are sidewalls having the convex portion and the concave portion.

[0019] In one embodiment, the thickness of the sidewall without the convex portion and the concave portion is greater than or equal to 2 mm and less than or equal to 8 mm.

[0020] This application provides a method for processing a glass container, the method comprising the following steps:

[0021] The top wall, the bottom wall, and the plurality of side walls are provided;

[0022] The top wall, the bottom wall, and the plurality of side walls are respectively placed in the welding cavity of the welding mold, wherein the inner contour shape of the welding cavity matches the outer contour shape of the glass container, so that the top wall, the bottom wall, and the plurality of side walls are respectively attached to the inner surface of the welding cavity, thereby splicing them together to form an initial container;

[0023] The welding mold containing the initial container is placed in a high-temperature device, and high-pressure gas is introduced into the initial container so that the initial container is tightly attached to the inner surface of the welding cavity under the action of the high-pressure gas, and the top wall, the bottom wall and the multiple side walls are fused together under the heating action of the high-temperature device.

[0024] The initial container inside the welding mold is cooled to allow the welded initial container to set and form the glass container.

[0025] Open the welding mold to remove the glass container.

[0026] The aforementioned glass container and its processing method, due to the presence of at least one convex and concave portion on at least one sidewall, forming a curved and undulating structure, enhance the elastic deformation capability of this at least one sidewall. When the glass container contains a product and is in a sealed state, if the external air pressure is higher than the internal air pressure, the sidewall is subjected to pressure from the outside inwards. The concave portion further deforms inwards, and the convex portion's protrusion decreases, i.e., it deforms inwards. This increases the internal air pressure of the glass container until it reaches equilibrium with the external air pressure, thus allowing the glass container to transition from its initial state of unequal elastic deformation to a first stable state. Similarly, if the internal air pressure of the glass container is higher than the external air pressure, the sidewall is subjected to pressure from the inside outwards. The convex portion further expands and deforms outwards, and the concave portion's concavity decreases, i.e., it deforms outwards. This decreases the internal air pressure of the glass container until it reaches equilibrium with the external air pressure, thus allowing the glass container to transition from its initial state of unequal elastic deformation to a second stable state. In this way, the glass container can become a bistable structure. When the external air pressure fluctuates or the internal air pressure changes, it can transform from the initial state of inelastic deformation to the first steady state or the second steady state, thereby balancing the internal and external pressure difference, reducing the risk of the glass container breaking under pressure, and improving the safety of the product.

Detailed Implementation

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0039] As stated in the background section, when a product is packaged in a thin-walled glass container, the container is sealed. Due to factors such as the volatilization of product components or product fermentation, the internal pressure of the thin-walled glass container will change. Because of its thin walls, the thin-walled glass container has lower mechanical strength. When the external air pressure fluctuates or the internal air pressure changes, the thin-walled glass container is prone to rupture under pressure, resulting in poor product safety.

[0040] Please combine Figures 1 to 3 One embodiment of this application provides a glass container 100, which includes a top wall 110, a bottom wall 120, and a plurality of side walls 130 connected end to end in sequence. The bottom ends of the plurality of side walls 130 are all connected to the bottom wall 120, and the top ends of the plurality of side walls 130 are all connected to the top wall 110, thereby defining the receiving cavity of the glass container 100 by the top wall 110, the bottom wall 120, and the plurality of side walls 130.

[0041] The wall material of at least one sidewall 130 is configured to have at least one convex portion 131 and at least one concave portion 132. The convex portion 131 has a first outer surface 1311 facing outward of the receiving cavity and a first inner surface 1312 facing inward of the receiving cavity. The first outer surface 1311 protrudes outward of the receiving cavity, and the first inner surface 1312 is concave outward of the receiving cavity.

[0042] The recessed portion 132 has a second outer surface 1321 facing the outside of the receiving cavity and a second inner surface 1322 facing the inside of the receiving cavity. The second outer surface 1321 is recessed towards the inside of the receiving cavity, and the second inner surface 1322 protrudes towards the inside of the receiving cavity.

[0043] It should be noted that the protruding portion 131 is formed by a portion of the wall material of the sidewall 130 itself, and is not an additional protruding portion provided on the sidewall 130. (Reference) Figure 2 The convex portion 131 has a first outer surface 1311 facing outward of the receiving cavity and a first inner surface 1312 facing inward of the receiving cavity. From an external viewpoint of the glass container 100, the first outer surface 1311 is an outwardly convex surface; from an internal viewpoint of the glass container 100, the first inner surface 1312 is a concave surface, and its concavity direction is towards the outside of the glass container 100. Therefore, the convex portion 131 is formed by a portion of the wall material of the sidewall 130 protruding outward as a whole, rather than by locally thickening the sidewall 130 to form the convexity.

[0044] Similarly, the recessed portion 132 is formed from a portion of the wall material of the sidewall 130 itself. (See reference) Figure 2 The recessed portion 132 has a second outer surface 1321 facing outward of the receiving cavity and a second inner surface 1322 facing inward of the receiving cavity. From an external viewpoint of the glass container 100, the second outer surface 1321 is a surface recessed into the glass container 100; from an internal viewpoint of the glass container 100, the second inner surface 1322 is a convex surface, and its protrusion is a recess into the glass container 100. Therefore, the recessed portion 132 is formed by an integral inward recess of a portion of the wall material of the sidewall 130 itself, rather than by locally slotting and thinning the sidewall 130.

[0045] Based on the ideal elastic properties of the glass substrate, the glass container 100 can undergo elastic deformation under pressure. Compared with traditional flat sidewalls, in this embodiment, the sidewall 130 has an outwardly convex portion 131 and an inwardly concave portion 132, which makes the sidewall 130 form a curved and undulating structure, thus making it easier to undergo elastic deformation under pressure and improving the elastic deformation capability of the sidewall 130.

[0046] The glass container 100 described above, having at least one sidewall 130 with an outwardly convex portion 131 and an inwardly concave portion 132 forming a curved and undulating structure, enhances the elastic deformation capability of the at least one sidewall 130. When the glass container 100 contains a product and is in a sealed state, if the external air pressure of the glass container 100 is higher than the internal air pressure, the sidewall 130 is compressed from the outside inward. The inwardly concave portion 132 further deforms in the inward direction, and the protrusion of the outwardly convex portion 131 decreases, i.e., it deforms inward. This increases the internal air pressure of the glass container 100 until it is balanced with the external air pressure, thus allowing the glass container 100 to transition from its initial state of unelastically deformed state to a first stable state. Similarly, if the internal air pressure of the glass container 100 is higher than the external air pressure, the sidewall 130 is compressed from the inside out. The convex portion 131 further expands and deforms outward, while the concave portion 132's indentation decreases, i.e., it deforms outward. This reduces the internal air pressure of the glass container 100 until it reaches equilibrium with the external air pressure. Thus, the glass container 100 can transition from its initial state of inelastic deformation to a second stable state. In this way, the glass container 100 can become a bistable structure. When the external air pressure fluctuates or the internal air pressure changes, it can transition from its initial state of inelastic deformation to either a first or second stable state, thereby balancing the internal and external pressure differences, reducing the risk of the glass container 100 rupturing under pressure, and improving product safety.

[0047] Please combine Figures 1 to 3 In some embodiments, the sidewall 130 includes a flat plate portion 133. The flat plate portion 133, the convex portion 131, and the concave portion 132 are integrally formed structures.

[0048] Specifically, in this embodiment, the flat plate portion 133 is the main body of the sidewall 130. In actual processing, the sidewall 130 can be first processed into a flat plate sidewall, and then the convex portion 131 and the concave portion 132 can be formed by hot bending. Thus, it can be understood that the sidewall 130 is originally a flat plate sidewall material, which is further processed to form a shape with the flat plate portion 133, the convex portion 131 and the concave portion 132.

[0049] In this embodiment, the sidewall 130 has a flat plate portion 133. Compared with the convex portion 131 and the concave portion 132, the flat plate portion 133 has higher rigidity, thus having better stability and maintaining the overall shape stability of the glass container 100.

[0050] In other embodiments, the sidewall having convex and concave portions may also exclude the flat plate portion. For example, such a sidewall may consist of a plurality of convex portions and a plurality of concave portions arranged alternately in sequence.

[0051] Please combine Figures 1 to 3In some embodiments, the convex portion 131 and / or the concave portion 132 define an inner region. The flat portion 133 includes a first portion 1331 located in the inner region and a second portion 1332 located outside the inner region.

[0052] Specifically, when the internal air pressure of the glass container 100 is greater than the external air pressure, the sidewall 130 is subjected to outward compression. However, the elastic deformation capacity of the flat portion 133 (compared to the convex portion 131 and the concave portion 132) is relatively poor. Therefore, under the internal pressure of the glass container 100, the first portion 1331 easily expands outward, thereby pulling the convex portion 131 and / or the concave portion 132 enclosed by its circumferential edge outward. This makes the convex portion 131 and / or the concave portion 132 more prone to outward deformation under the action of the first portion 1331, further enhancing the elastic deformation capacity of the sidewall 130 under internal pressure. (Reference) Figure 2 It is understood that when the first part 1331 expands outward, the relative angle α between the first part 1331 and the adjacent convex part 131 or concave part 132 on both sides increases.

[0053] Similarly, when the external air pressure of the glass container 100 is greater than the internal air pressure, the sidewall 130 is subjected to inward compression, but the elastic deformation capacity of the flat portion 133 (compared to the convex portion 131 and the concave portion 132) is relatively poor. Therefore, under the internal pressure of the glass container 100, the first portion 1331 easily expands inward, thereby pulling the convex portion 131 and / or the concave portion 132 enclosed by its circumferential edge inward. This makes the convex portion 131 and / or the concave portion 132 more prone to greater inward deformation under the action of the first portion 1331, further enhancing the elastic deformation capacity of the sidewall 130 under external pressure. (Reference) Figure 2 It is understood that when the first part 1331 expands inward, the relative angle α between the first part 1331 and the adjacent convex part 131 or concave part 132 on both sides decreases.

[0054] Preferably, the internal region is located in the central region of the sidewall 130. When the glass container 100 is subjected to internal or external air pressure, the pressure mainly acts on the central region of the sidewall 130, making it easier for the first part 1331 to stretch and deform the convex part 131 and the concave part 132.

[0055] Preferably, the convex portion 131 extends smoothly along its length direction, meaning there are no abrupt changes in curvature along its extension direction; for example, it may extend along an arc-shaped trajectory.

[0056] Preferably, the concave portion 132 extends smoothly along its length direction, meaning there are no abrupt changes in curvature along its extension direction; for example, it may extend along an arc-shaped trajectory.

[0057] Please combine Figures 1 to 3 In some embodiments, along the enclosure direction of the inner region, the convex portion 131 extends to form a circumferential closed structure, and the concave portion 132 extends to form a closed structure, with the convex portion 131 and the concave portion 132 adjacent to each other.

[0058] In this embodiment, the protruding portion 131 extends to form a circumferentially closed structure, that is, the protruding portion 131 surrounds and forms a closed circle. Figure 1 In the illustrated embodiment, the extension trajectory of the convex portion 131 is approximately elliptical or elliptical in shape. Understandably, the extension trajectory of the convex portion 131 can also be circular or other shapes. Similarly, the concave portion 132 forms a closed loop. Figure 1 In the embodiment shown, the extension trajectory of the concave portion 132 is approximately elliptical or elliptical in shape. Understandably, the extension trajectory of the concave portion 132 can also be circular or other shapes.

[0059] In this context, "the convex portion 131 and the concave portion 132 are adjacent" means that there is no space between the convex portion 131 and the concave portion 132; they are directly adjacent. Thus, in this embodiment, the convex portion 131 and the concave portion 132 form a structure that surrounds each other layer by layer from the inside out, with the innermost region defined by either the innermost convex portion 131 or the innermost concave portion 132. The innermost convex portion 131 or the innermost concave portion 132 is the portion directly adjacent to the first portion 1331. The second portion 1332 is the portion located in the outer region of this layered structure.

[0060] In this embodiment, the convex portion 131 extends to form a circumferential closed structure, and the concave portion 132 extends to form a closed structure. The circumferential closed structure (compared to the circumferential non-closed structure) can better disperse stress, thereby making the sidewall 130 less prone to cracking.

[0061] In other embodiments, the convex portion 131 may also extend to form a non-closed structure, for example, its extension trajectory is an arcuate groove structure with an opening; similarly, the concave portion 132 may also extend to form a non-closed structure, for example, its extension trajectory is an arcuate groove structure with an opening.

[0062] In another embodiment, the internal region can also be defined by the convex portion 131 and the concave portion 132. For example, the extension trajectory of the convex portion 131 is a first arcuate groove structure with a first opening, and the extension trajectory of the concave portion 132 is a second arcuate groove structure with a second opening. The first opening of the first arcuate groove structure is opposite to the second opening of the second arcuate groove structure, so that the convex portion 131 and the concave portion 132 can jointly form an internal region.

[0063] Alternatively, the convex portion 131 and the concave portion 132 may not form an internal region; for example, their extension directions may be straight.

[0064] In some embodiments, the junction between the convex portion 131 and / or the concave portion 132 and the flat portion 133 is smoothly transitioned.

[0065] exist Figures 1 to 3 In the illustrated embodiment, the sidewall 130 has multiple protruding portions 131 and multiple concave portions 132, which are arranged alternately to form a layered, surrounding structure. The innermost layer of this layered structure is a concave portion 132, which is connected to the first portion 1331 with a smooth transition at the connection point. The outermost layer of this layered structure is another concave portion 132, which is connected to the second portion 1332 with a smooth transition at the connection point.

[0066] In this embodiment, the smooth transition at the joint between the convex portion 131 and / or the concave portion 132 and the flat portion 133 can minimize stress concentration at the joint.

[0067] In some other embodiments, the convex portion 131 may be connected to the flat portion 133 and the connection may be smooth. For example, when the innermost and / or outermost layer of the above-mentioned layered structure is the convex portion 131, the convex portion 131 is connected to the first portion 1331 and / or the second portion 1332, so that the connection between the convex portion 131 and the first portion 1331 and / or the second portion 1332 can be smooth.

[0068] Alternatively, the convex portion 131 may be connected to the flat portion 133 with a smooth transition at the joint, and the concave portion 132 may be connected to the flat portion 133 with a smooth transition at the joint. For example, the innermost and outermost layers of the above-mentioned layered structure may be the convex portion 131 connected to the first portion 1331 and the concave portion 132 connected to the second portion 1332, or the concave portion 132 connected to the first portion 1331 and the convex portion 131 connected to the second portion 1332.

[0069] Please refer to Figures 1 to 3In some embodiments, there are multiple convex portions 131 and multiple concave portions 132, and the convex portions 131 and concave portions 132 are arranged alternately in sequence.

[0070] The deformation capability of the sidewall 130 can be further enhanced by multiple alternating convex portions 131 and concave portions 132.

[0071] In other embodiments, the convex portion 131 and the concave portion 132 may each be one.

[0072] In some embodiments, the convex portion 131 and the concave portion 132 are adjacent to each other, that is, they are directly connected without being separated by a flat plate portion.

[0073] In one embodiment, any two adjacent walls of the top wall 110, bottom wall 120, and multiple side walls 130 are fused together.

[0074] Specifically, the glass container 100 targeted in this application embodiment is a thin-walled glass container, which cannot usually be prepared by blow molding. Instead, it is made by forming each wall separately in pieces and then welding the walls together.

[0075] In one embodiment, the glass container 100 further includes a closure (not shown), such as Figures 1 to 3 As shown, the top wall 110 is provided with a container opening 101, and a closure is connected to the top wall 110 and used to close the container opening 101 to seal the glass container 100. The closure is, for example, a container plug or a container cap.

[0076] In one embodiment, the thickness of the bottom wall 120 is greater than the thickness of each side wall 130, and the thickness of the bottom wall 120 is greater than or equal to 3 mm and less than or equal to 10 mm.

[0077] The bottom wall 120 serves as the support for the entire glass container 100, and its relatively large thickness helps to ensure the support strength of the glass container 100.

[0078] Please combine Figures 1 to 3 In one embodiment, among the plurality of sidewalls 130, there are two first sidewalls 130a opposite each other along a first direction YY' and two second sidewalls 130b opposite each other along a second direction XX', where the first direction YY' and the second direction XX' intersect. The width of the first sidewall 130a is greater than the width of the second sidewall 130b, and the thickness of the first sidewall 130a is less than the thickness of the second sidewall 130b. Both first sidewalls 130a are sidewalls 130 having an outwardly convex portion 131 and an inwardly concave portion 132.

[0079] Specifically, in combination Figures 1 to 3As shown, the first direction YY' is the relative direction of the two first sidewalls 130a, the second direction XX' is the relative direction of the two second sidewalls 130b, and the third direction ZZ' is the height direction of the glass container 100.

[0080] Optionally, the first direction YY', the second direction XX', and the third direction ZZ' are perpendicular to each other. The width of the first sidewall 130a (i.e., the dimension of the first sidewall 130a in the second direction XX') is greater than the width of the second sidewall 130b (i.e., the dimension of the second sidewall 130b in the first direction YY'). Therefore, the first sidewall 130a is a sidewall with a larger area than the second sidewall 130b.

[0081] In this embodiment, by constructing convex portions 131 and concave portions 132 on a sidewall 130 with a large area, longer and more convex portions 131 and concave portions 132 can be arranged, thereby further improving the deformability of the sidewall 130.

[0082] In this way, by making the thickness of the first sidewall 130a less than the thickness of the second sidewall 130b, that is, the wall thickness of the first sidewall 130a is thinner, it is more conducive to the elastic deformation of the first sidewall 130a under pressure.

[0083] In other embodiments, the second sidewall 130b may also have a convex portion and a concave portion. In other embodiments, the first direction YY' and the second direction XX' may not be perpendicular, for example, they may have a certain tilt angle. Other sidewalls may also be provided between the first sidewall 130a and the second sidewall 130b instead of a direct connection.

[0084] It should be noted that the glass container can have four side walls, namely the two first side walls and two second side walls in the above embodiment. The glass container can also have any number of side walls, such as two, three, five, or six.

[0085] For example, when the glass container has two sidewalls, one sidewall is an arc-shaped sidewall, and the other sidewall is the one with the convex portion 131 and the concave portion 132 described above. This concave sidewall is connected to both ends of the arc-shaped sidewall, thus forming a circumferentially closed sidewall structure. When the glass container has three sidewalls, the three sidewalls are connected end-to-end in sequence, thus forming a circumferentially closed sidewall structure. Similarly, the sidewall structures of glass containers with five or six sidewalls can be understood.

[0086] Of the multiple sidewalls of the glass container, apart from the sidewall with the convex portion 131 and the concave portion 132 described above, the shape of any other sidewall can be a flat plate structure or a curved plate structure (e.g., an arc-shaped sidewall, a wavy sidewall, etc.). The top wall of the glass container can be a flat plate structure or a curved plate structure, and the bottom wall of the glass container can be a flat plate structure or a curved plate structure.

[0087] Since the multiple sidewalls of the glass container are connected end to end in sequence, in any two adjacent sidewalls of the glass container, one side of one sidewall (called the first sidewall) is connected to one side of the other sidewall (called the second sidewall), and the shape of the first sidewall matches the shape of the second sidewall, so that the two adjacent sidewalls can be sealed together through the first sidewall and the second sidewall.

[0088] For example, in any two adjacent sidewalls of a glass container, if the outer contour of one sidewall is a parallelogram and the first side is an inclined side, then the outer contour of the other sidewall can also be a parallelogram and the second side is an inclined side; or, in any two adjacent sidewalls of a glass container, if the outer contour of one sidewall is a rectangle and the first side is a vertical side, then the outer contour of the other sidewall can also be a rectangle and the second side is a vertical side.

[0089] It is understandable that the outer contour shape of each sidewall in a glass container can be any polygon. For example, the outer contour shape of the sidewall can be a rectangle, a square, a trapezoid, a parallelogram, or other shapes, as long as the shape of the first side of one sidewall matches the shape of the second side of the other sidewall, so that the two adjacent sidewalls can be sealed and connected by the first sidewall and the second sidewall.

[0090] Please refer to Figure 2 Combination Figures 1 to 3 In one embodiment, the sidewall 130, which has an outwardly convex portion 131 and an inwardly concave portion 132, has a flat portion 133 with a thickness H that satisfies the condition: 1.5mm ≥ H ≥ 0.05mm. This allows the sidewall 130 to be relatively thin, which is beneficial for the sidewall 13 to undergo elastic deformation.

[0091] The sidewall 130 having an outwardly convex portion 131 and an inwardly concave portion 132 is, for example, the first sidewall 130a described above.

[0092] In one embodiment, the thickness of the sidewall 130, which does not have the protruding portion 131 and the concave portion 132, is greater than or equal to 2 mm and less than or equal to 8 mm. This allows the sidewall 130 to have greater rigidity, thereby improving the stability of the glass container 100.

[0093] A sidewall 130 that does not have an outwardly protruding portion 131 and an inwardly recessed portion 132 is, for example, the second sidewall 130b described above.

[0094] Please combine Figures 1 to 3 In one embodiment, the vertical distance B between the highest point of the first outer surface 1311 and the lowest point of the second outer surface 1321 satisfies the condition: B > 1.5H, where H is the thickness of the plate portion 133, and the vertical distance B refers to the distance between the highest point and the lowest point along the thickness direction of the plate portion 133.

[0095] By making the vertical distance B between the highest point of the first outer surface 1311 and the lowest point of the second outer surface 1321 greater than 1.5H, the elastic deformation space of the convex portion 131 and the concave portion 132 can be made larger, which is conducive to the convex portion 131 and the concave portion 132 having sufficient deformation amplitude in the thickness direction of the flat plate portion 133, thereby fully absorbing pressure fluctuations.

[0096] Please combine Figures 1 to 3 In one embodiment, the distance D between the highest points of two adjacent convex portions 131 satisfies the condition: 8B > D > 2B, where B refers to the vertical distance between the highest point of the first outer surface 1311 and the lowest point of the second outer surface 1321.

[0097] The distance D between the highest points of two adjacent convex portions 131 is equal to the distance between the lowest points of two adjacent concave portions 132. A ripple is formed by one convex portion 131 and one concave portion 132, and the distance D is the straight-line length of one ripple cycle.

[0098] By setting 8B > D > 2B, a corrugation cycle can be made long enough, which allows the corrugated structure to undergo more elastic deformation.

[0099] Please refer to Figure 4 An embodiment of this application also provides a method for processing a glass container, used to process a glass container as described in any of the above embodiments, the processing method comprising the following steps:

[0100] S100: Provides a top wall 110, a bottom wall 120, and the plurality of side walls 130.

[0101] Specifically, the top wall 110, bottom wall 120, and the plurality of side walls 130 can be pre-processed, that is, the various walls for splicing the glass container 100 are prepared in advance.

[0102] S200: The top wall 110, bottom wall 120 and the plurality of side walls 130 are respectively placed in the welding cavity of the welding mold, wherein the inner contour shape of the welding cavity matches the outer contour shape of the glass container, so that the top wall 110, bottom wall 120 and the plurality of side walls 130 are respectively attached to the inner surface of the welding cavity, thereby splicing them together to form an initial container.

[0103] Specifically, in this step, the top wall 110, bottom wall 120, and the plurality of side walls 130 are respectively placed inside the welding cavity of the welding mold. Since the inner contour shape of the welding cavity matches the outer contour shape of the glass container, that is, the welding cavity has a top inner surface that can fit against the outer surface of the top wall 110, a bottom inner surface that can fit against the outer surface of the bottom wall 120, and a plurality of side inner surfaces that can fit against the outer surfaces of the plurality of side walls 130. Thus, when the top wall 110, bottom wall 120, and the plurality of side walls 130 are placed inside the welding cavity of the welding mold, the top wall 110, bottom wall 120, and the plurality of side walls 130 can respectively fit against the corresponding surfaces (top inner surface, bottom inner surface, and plurality of side inner surfaces) within the welding cavity, thereby allowing the top wall 110, bottom wall 120, and the plurality of side walls 130 to be joined together to form the initial container.

[0104] Understandably, in this step, the top wall 110, bottom wall 120, and the plurality of side walls 130 are joined together, but not yet fused; that is, they are not securely fixed together. Therefore, the initial container's outline is basically consistent with the outline of the formed glass container, but the walls of the initial container are not yet securely fixed together.

[0105] S300: The welding mold containing the initial container is placed in a high-temperature device, and high-pressure gas is introduced into the initial container so that the initial container is tightly attached to the inner surface of the welding cavity under the action of the high-pressure gas, and the top wall 110, bottom wall 120 and multiple side walls 130 are welded together under the heating action of the high-temperature device.

[0106] Specifically, the pressure value of the high-pressure gas can be set according to the requirements of the actual processing conditions. This embodiment does not specifically limit the pressure range of the high-pressure gas, as long as the gas pressure is sufficient to ensure that each wall of the initial container is tightly attached to the inner surface of the welding cavity. This embodiment does not specifically limit the heating temperature of the high-temperature equipment, as long as the top wall, bottom wall, and multiple side walls are able to weld together. When introducing high-pressure gas into the initial container, it can be introduced through the container opening 101 of the initial container, i.e., the container opening 101 located on the top wall 110.

[0107] During the welding process of the walls of the initial container under the heating action of the high-temperature equipment, the walls of the initial container can be tightly attached to the inner surface of the welding cavity by the action of high-pressure gas. Thus, the inner surface of the welding cavity can shape the outer surface of the walls of the initial container, ensuring that the shape and dimensional accuracy of the walls of the initial container still conform to the shape and dimensional accuracy of the glass container 100 after welding.

[0108] S400: Cools the welding mold and its internal initial container to allow the initial container to set after welding, forming a glass container.

[0109] After welding is completed, the walls of the initial container remain in an unformed state under high temperature. In this step, the initial container inside the welding mold is cooled down and formed, thus creating a stable glass container 100.

[0110] Specifically, cooling can be achieved by gradually reducing the heating temperature of the high-temperature equipment. During the initial cooling stage, the initial container is not yet set; therefore, high-pressure gas must continue to be introduced into the initial container to ensure that all walls of the initial container are tightly attached to the inner surface of the welding cavity. Once the initial container has set, the introduction of high-pressure gas can be stopped.

[0111] S500: Open the welding mold to remove the glass container 100.

[0112] By opening the welding mold, the shaped glass container 100 can be easily removed.

[0113] In one embodiment, the welding mold is provided with an air extraction port, which communicates with the welding cavity. During the actual welding process, a small amount of air may exist within the welding cavity, resulting in a small air gap between the outer surface of the initial container and the inner surface of the welding cavity, affecting the tightness of the fit between the initial container and the welding cavity. Therefore, in this embodiment, the glass container processing method further includes performing step S600 before step S400. S600 includes: extracting the air between the outer surface of the initial container and the inner surface of the welding cavity through the air extraction port. This facilitates a tighter fit between the outer surface of the initial container and the inner surface of the welding cavity, thereby improving the dimensional accuracy of the glass container.

[0114] Specifically, in step S300, after high-pressure gas is introduced into the initial container for a certain period of time (e.g., after 30 to 100 seconds at saturation), step S600 can be executed.

[0115] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0116] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
